L-glutamine
PubChem Notes:
Glutamine A non-essential amino acid present abundantly throughout the body and is involved in many metabolic processes. It is synthesized from GLUTAMIC ACID and AMMONIA. It is the principal carrier of NITROGEN in the body and is an important energy source for many cells.
Glutamine - definition from Biology-Online.org
[(Science: amino acids) One of the 20 amino acids commonly found (and directly coded for) in proteins. It is the amide at the _ carboxyl of the amino acid glutamate. glutamine can participate in covalent cross linking reactions between proteins, by forming peptide like bonds by a transamidation reaction with lysine residues. this reaction, catalysed by clotting factor XIII stabilises the aggregates of fibrin formed during blood clotting. media for culture of animal cells contain some 10 times more glutamine than other amino acids, the excess presumably acting as a carbon source.

[1. The ΄-amide of glutamic acid, derived by oxidation from proline in the liver or by the combination of glutamic acid with ammonia; the l-isomer is present in proteins, blood, and other tissues, and is an important source of urinary ammonia, being broken down in the kidney by the action of the enzyme glutaminase; nonenzymatically, it is converted to 5-oxoproline.
